OLAMEING DEVICE.

Application filed July 5, 1823. Serial No. 649,504.

To all whom it may concern: 7

Be it known that I, GEORGE C. HUME, a citizen of the United States, residing at Chilton, in the county of Calumet and State of Wisconsin, have invented certain new and useful Improvements in Clamping Devices, of which the following is a specification.

This invention relates to devices for clamping bags to grain delivery chutes, and for other similar purposes; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed. a

In the drawings, Figure 1 is a front view of a clamping device constructed according to this invention. Fig. 2 is a plan view. Fig. 3 is a vertical section, taken on line 33 in Fig. 1.

A supporting plate 5 isprovided, and is rigidly secured to a grain delivery chute or other similar object. One end of this plate is provided with two parallel hook-shaped arms 6 separated by a longitudinal channel. The plate and its arms a-rg preferably formed of a single piece of metal. A pin 9 is secured in the end portions 8 of the arms, which overlap the plate 5,and an eccentric toothed block or jaw 10 is mounted to oscillate on the pin 9. The upper part 12 of the 3 jaw or block 10 is made thickand heavy so that its toothed surface is'normallv pressed towards the plate 5, as shown in Fig. 3, and an operating handle 14 is secured to the jaw to afford a means for moving it away from the plate 5. The pin 9 preferably has reduced end portions 15 which engage with holes in the parts 8 and are riveted in place.

The upper part of the plate 5 has a lug 7 which projects over the jaw 10, and is provided with a slot 18 for the handle 14 to work in. The slot limits the movement of the handle and prevents the jaw from being moved too far away from the plate The bag, or other similar article. 16, is thrust between the toothed jaw and the plate 5, as shown in dotted lines in Fig. 3, and the toothed jaw engages with the article.

The jaw is held in engagement with the article automatically because of its eccentric form. An increase of weight put on the article, as in filling a ba only increases the grip of the jaw, and clamps the article more tightly against the plate.

What I claim is:

A clamping device for bags comprising a supporting plate provided at one end with a lug which projects laterally from it at substantially a right angle and is provided with a slot, said plate having also two arms which project laterally of it under the said lug, an eccentric clamping block pivoted between the said arms upon a pin arranged crosswise of the said slot and adapted to clamp a bag against the said plate, and a handle secured to the said block and projecting through the said slot and limiting the movement of the block away from the said plate by contact with the outer end of the said slot.

In testimony whereof I have afiixed my signature.

GEORGE C. HUME.
